The CS35L01/03 features an advanced closed-loop ar- chitecture to provide 0.02% THD+N at 1 W and -75 dB PSRR at 217 Hz. A flexible Hybrid Class-D output stage offers four modes of operation: Standard Class-D (SD) mode of- fers full audio bandwidth and high audio performance; Hybrid Class-D (HD) mode offers a substantial reduc- tion in idle power consumption with an integrated Class- H controller; Reduced Frequency Class-D (FSD) mode reduces the output switching frequency, producing low- er electromagnetic interference (EMI); and Reduced Frequency Hybrid Class-D (FHD) mode produces both the lower idle power consumption of HD mode and the reduced EMI benefits of FSD mode. Requiring minimal external components and PCB space, the CS35L01 and CS35L03 are available in a 1.2 mm x 1.2 mm, 9-ball WLCSP package in Commer- cial grade (-10°C to +70°C). Please see “Ordering Information” on page 33 for package options and gain configurations. CS35L01/03 APR '10 DS909A2 |
